FO on raw data greatly increase MY workload, and the risk of errors, track deviations and altitude busts increases.
And the corollary is, perhaps, even more pertinent:

CAPT on raw data greatly increase MY workload, and the risk of errors, track deviations and altitude busts increases.
Embracing this philosophy, are we going to be feeling better or worse when, in IMC with a FD failure, possibly OEI, you have do this for real?

There is a time and place for everything?

But the original poster recounts the experience of a colleague who says that, whilst this is an admirable sentiment, time isn't afforded him/her, even in the sim, to practice raw data flying. So just when does he/her get this experience?

I didn't learn to get my knee down at 120mph on my bike without having a go. Thankfully, I only fell off once during the learning process!

Its another example of paying lip service to safety.

When was the last time you had a FD failure during an EFATO or at any subsequent point during a check?

Centaurus,

Your colleagues experience agrees with my own. Personally I'll take a raw-data/visual approach whenever I can but the range of reactions from the guy/gal in the other seat vary tremendously.

Switch everything off, go direct to 10 mile final from VILNA for RW10 at ALC in day VMC?

Oooooo...don't know about that.

You what????

Am I driving this thing, or is it driving me?

Operators / captains should remember that raw data flight need not be as accurate as automatic flight; it only has to be sufficient for safety. This understanding should remove unnecessary pressure both from the PF and the captain, but in turn this requires knowledge of what is sufficient for safety – see rules and procedures.
Brilliant point.

I made some comments in another thread about how the real test of your safe operation is how your perform when things start going wrong.

16hrs/year isn't enough to ensure that, bearing in mind the complexity of a modern commercial airliner flightdeck, you can deal with the effects of certain failures, that whilst being statistically rare, are operationally, enormously significant.

Seat1APlease,

Its a topsy-turvy world!
